Stock Trading

For anyone who has started their own home business or made a career for themself at home. I am interested in starting a business or finding something that I can do from my home, possible using the computer. I have not come up with an idea yet. But I'd like to hear from anyone who has done something like this and hear what you think about working from home. Are you/have you been successful? I am NOT out to "steal" anyones business idea, so you don't have to share exactly what you do, if you do not want to. Just curious if I should do it or not.

I am a 17 year old teenager and i want some tips on how to get started in playing the stock market?

You are young - so I guess you have a riskier trading profile than older people. You have the time to earn back money you lose - so perhaps most of your "playing" would be high risk high return ventures / trading. Have a look at CFDs (http://www.mysharetrading.com/trading-topics/derivatives-cfds) and other derivatives for a little leverage.

When trading stocks on NYSE I find stocks with ask/buy prices marked N/A. How do I acquire these stocks?

When I am trading stocks on yahoo finance I come across stocks like AK Steel that have a bid price marked N/A and an Ask price marked N/A. How do I purchase shares of these stocks?

1. Trading Halt.
2. No liquidity. there are currently no bids on the market to buy or offers to sell their stock.

If it is a trading halt - you can't buy them until the halt has been lifted.
If it has no liquidity, simply put up a bid price at which you are comfortable to buy them at.
